when you nmap your machine are you doing against internet address or intranet address?
your adsl-router may have a web interface for administration....
if you have an pppoe connection and just one ethernet interface, shutdown pppoe and run nmap against eth0 interface. after, bring pppoe up and run nmap against pppx interface. report here the diferences

I did a test and run nmap against ip adsl-router and the result is the egual the host ip address.

Another test, i run nmap against others three hosts with adsl connection and the result is egual. The port 80 is open or filtered on both cases.

My hosts is clean?

Thanks by help.

Sounds to me like a webmin configuration page for the router. Have you actually gone to the page?

Go to a computer outide of your network and telnet to you ip address. The command looks like this:

Quote:

telnet x.x.x.x 80

If the telnet connects, then issue this command:

Quote:

GET / HTTP / 1.1

That will give you a good bit of info right there. If it does not connect, try it in a web browser.

If not, then just look at the config for your router, for some odd reason it may have port 80 opened up. If it is and you arn't using it, close it.
